“…In water scarcity, the unfavorable plant height emerged in genotypes NIA Sunder, Benazir, and TJ-83, with a plant height average reduced by 6.60. Hence, the superior in this trait was minimum height observed in Hamal Fakir, TD-1, and Imdad-05, highlighted as desirable plants for under water stress conditions; therefore, these cultivars proved drought-fighters, agreeing with the results by Nikzad et al (2022) and Tamrazov (2022), who also examined that the (5.98%) decline in plant height occurred in waterstopped conditions.…”

“…The drought stress treatments were applied as described by Nikzad et al 44 . The irrigation depth was calculated using the following formula: I = [(FC − θ )/100] D × B); where I is irrigation depth (cm), FC (− 0.03 MPa) is soil gravimetric moisture percentage at field capacity (22%), θ (− 1.5 MPa) is soil gravimetric moisture percentage at irrigation time (10%), D is root-zone depth (50 cm), and B is soil bulk density at the root zone (1.3 g cm −3 ) 45 .…”

Drought tolerance is a complex trait in plants that involves different biochemical mechanisms. During two years of study (2019–2020), the responses of 64 arugula genotypes to drought stress were evaluated in a randomized complete block design with three replications under field conditions. Several metabolic traits were evaluated, i.e. relative water content, photosynthetic pigments (chlorophyll and carotenoids), proline, malondialdehyde, enzymatic antioxidants (catalase, ascorbate peroxidase, and peroxidase), total phenolic and flavonoid contents and seed yield. On average, the drought stress significantly increased the proline content (24%), catalase (42%), peroxidase (60%) and malondialdehyde activities (116%) over the two years of study. As a result of the drought stress, the seed yield (18%), relative water content (19.5%) and amount of photosynthetic pigments (chlorophyll and carotenoids) dropped significantly. However, the total phenolic and flavonoid contents showed no significant changes. Under drought stress, the highest seed yields were seen in the G50, G57, G54, G55 and G60 genotypes, while the lowest value was observed in the G16 genotype (94 g plant−1). According to the findings, when compared to the drought-sensitive genotypes, the drought-tolerant arugula genotypes were marked with higher levels of proline accumulation and antioxidant enzyme activity. Correlation analysis indicated the positive effects of peroxidase, catalase and proline on seed yield under drought conditions. These traits can be considered for the selection of drought-tolerant genotypes in breeding programs.

“…Both indices offer a quantitative and objective approach to selecting superior genotypes and are frequently used in the selection of materials across various crops such as common bean (Phaseolus spp. ), maize (Zea mays), sugarcane (Saccharum officinarum), passion fruit (Passiflora edulis), arugula (Eruca sativa L.), among others (KRAUSE et al, 2021;RIBEIRO and MAZIERO, 2023;NIKZAD et al, 2023).…”

Ornamental peppers (Capsicum spp.) possess several characteristics of interest used in species breeding programs for selection purposes. Selection indices are useful and essential tools that allow simultaneous selection based on various characteristics. Although there are various available indices, do they differ in indicating the best genotypes? This study aimed to estimate genetic parameters to identify variables with moderate to high heritability and subject them to different selection indices in an F3 population of ornamental pepper, observing the congruences in identifying the genotypes to be selected. 400 genotypes in the segregating F3 generation were considered. The trial was conducted in a greenhouse. The variables used were plant height, time to maturity, fruit quantity per plant, and average fruit mass. Genetic parameter estimates were obtained using the REML method for each variable, and subsequently, variables showing moderate to high heritability (Resende, 2002a) were considered for simultaneous selection. The selection indices Mulamba & Mock (MM) and Multiplicative Index (IM) were employed to predict genetic gains, with a selection pressure of 20%. Both indices showed high estimates of genetic gains. MM presented the highest values (ranging from 57.49% to 309.37%), while the multiplicative index varied from 55.53% to 199.2%. The applied selection indices proved suitable for genotype selection due to the high predicted genetic gains. Among the 80 selected genotypes, only 12.5% were present in both indices but in different positions in the rankings. The results showed inconsistencies between the indices in indicating the best genotypes.
